A communications system (100) has at least one TDD platform pair (130, 200) operating synchronously using a Time Division Duplex (TDD) frame structure. A TDD platform pair (130, 200) has first communications platform (124) and second communications platform (126) that are coupled (135) together. First communications platform (124) transmits first data during a first frame and receives second data during a second frame. Second communications platform (126) receives third data during the first frame and transmits fourth data during the second frame. At least one TDDSU (110) receives the first data, transmits the second data, transmits the third data, and receive the fourth data. First communications platform (124) has a first coverage area, and the second communications platform (126) has a second coverage area. A dual coverage area exists where the first coverage region overlaps the second coverage region. At least one TDDSU (110) is located within the dual coverage region.
